To 04% whont it may concern.-

Be it known that I, TOMMASO DI TULLro, of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Boiler-Oleaning Compounds, of which the following is a specification.

The above-mentioned ingredients are mixed in a dry, powdered or granular form, producing a dry compound which is soluble in waterqgf A suitable quantity of the said composition added to the charge of water in a steam boiler will act quickly and efliciently in removing rust, scale and other foreign matter deposited on the surfaces of the boiler.

2. A boiler-cleaning composition consisting of extract quebraoha, bicarbonate of soda, sal ammoniac, pulvis eucalyptus, crystallized soda and Chinese soda.
